1 Application filed fiepteinbcr 19, 1924. Serial No. 738,631.

To all to 7mm may 00 earn lie it known that l, STANISLAW l dEOI-IA' ran, a citizen of the United States, residing at Toledo, in the county of areas and State of Ohio, have invented new and useful linproveinents in Spark Arresters, of which the following is a s 'ieciiication.

, My invention relates to spark arresters especially adapted for chimneys and the like. i

An object of the invention is to provide a tachcd to a chimney and which will prevent the discharge of hot sparks and yet not interfere with the discharge of smoke.

A further object of the invention is to provide an extension for chimneys having a battle plate for deflecting the sparks and branch passages encircling the battle plate through which the smoke is conducted.

Another object of the invention is. to pro vide a device of the above mentioned charactor which is simple and dural'ile in construction, reliable and et'ticient in use and inexpensive to manufacture.

. Other objects and advantages of the invention will be apparent during the course oi the following description.

re the accompanyingdrawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1, is a side elevation ot the attachment,

.lTig. 2, is a the same,

i Fig. 3, is atop view, and,

Fig. 4;, is a ci.'osssection ou lines' .t-i Ol his. 2.

iii the drawing, wherein tor the purpose of illustration have shown a preferred cuibodinient oi my invention, the nun'icral 5 denotes a tubular pipe provided a its lower end with a square base 6 having; depending flanges 7 adapted tobe lit-ted over the top" 01 a chimney (not shown) and secured thereto by set screws 8. lizlounted within the pipe adjacent the upper end thereof is an inverted truncated cone shaped bali'le plate smoke and sparks emitted from the chimney in passing through the pipe will strike the. battle plate 9, causing the sparks to be delongitudinal sectional view oi fiected down into the chimney and the smoke diverted into the are shaped tubular branch passages 10. These passages will vary in number according; to the size of the chimney and are disposed longitudinally of the pipe in spaced relation. The lower ends of the passages are connected to the pipe below the baflle plate, as at 11, and the upper ends connected to the pipe above the baffle plate, as at 12, so the smoke will he conducted around the baffle plate and discharged out of theupper end of the pipe. The upper end 01 the pipe is flared outwardly, as at 1.3, and a conical shaped cap 1 1 is supported above the pipe in spaced relation by. the verticalbrackets 15 protecting the chimney from rain and dirt. The base of the cap extendsbeyond the edge of the pipe being on a horizontal plane therewith,

so the smoke and cinders will be deflected downwardly. Should dirt or cinders accumulate on the battle plate, it will be discharged through the opening 16 in the baffle plate. i

Thus it is seen, that in use this attachment will prevent the discharge of hot sparks from the chimney, thereby eliminating the danger of the resulting from flying sparks and yet will not interfere with the draft of the chimney or discharge of the smoke.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preterred example of the same and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

l laving thus described my invention 1 claim:

1. A device of the character described ineluding a pipe, an inverted truncated cone shaped battle plate mounted within said pipe, and a plurality of branch passages having one end connected to said pipe below said battle plate and their opposite ends connected to said pipe above said bafile plate.

2. A device of the character described including a pipe, an inverted truncated cone shaped baffle plate mounted within .isaid pipe, a pluralityof are shaped branch pas sages having connection. with said pipe passages disposed longitudinull 0'! said above and below said baflle plate, and means plpe havmg connection therewith above and for connecting said pipe to a chimney. belon said baflle plate. 10

3. A device f the hara t d ib d i In testimony whereof I aihx my signaeluding a plpe, an lnverted truncated cone tutesha-ped bafile plate mounted Within said pipe, and a plurality of are shaped branch STANISLAV MICHA AK.
